【摘要】 论文回顾了锗在锌电积过程中行为的研究成果,认为电解液中锗的存在不仅影响电流效率,沉积物形貌,还改变电积锌的极化行为。当电解液中存在明胶,铅离子,铊离子等添加剂时,锗的有害影响会得到缓解。尽管如此,有关锗离子阴极还原机理(如电极反应参数的测定及电极反应历程等)以及锗与多种杂质及添加剂相互作用机理仍需进一步深入研究。更多还原

【Abstract】 The research status of behavior on germanium in zinc electrowinning from acid sulphate electrolyte was simply reviewed.It is germanium,exists in acid sulphate electrolyte, which may affect the current efficiency and deposit morphology,change polarization behavior.But when electrolyte contained gelatin,Pb²⁺and TI³⁺ etc.,awful effects of germanium could be reduced. However,correlative mechanism such as cathode reduction of Ge⁴⁺and interaction between Ge⁴⁺ and multi-impurities still need to be studied further.更多还原
